You might have noticed that the cost of food has gone up.In fact the price of wheat and rice has nearly doubled in the past few years.It’s thought that right now，850 million people—that’s more than 10 times the population of the UK—are short of food because it’s too expensive or there’s not enough of it.

The price of basic food such as wheat and corn has stayed the same for quite a long time，about 30 years.But as the world’s population is getting bigger，there’s more pressure to feed more people，plus there’s less land and water to go round.

Another reason is climate（氣候）change.Droughts and floods make it hard to grow crops like rice and grain.The price of oil has gone up and that makes it more expensive for farmers to run their tractors and to transport the food they make.And lots of fields are being used to grow crops to make other things that can’t be eaten—which is bad news for hungry people.

The main losers are poor people who live in cities in poor countries，who are facing higher prices for food.Some people are doing well out of the food crisis（危機(jī)） though.Farmers in rich countries like the US，Canada and Australia are getting record prices for their harvests.

World leaders are meeting in the Italian capital Rome to talk about the problem of rising food prices.Some countries are helping out with the cost of foods and international aid agencies have called for more money for food production in poor countries.

Tony: These days, the word “clone” has appeared very often in the newspapers. Do you know its meaning?
Lana: I read a report. It said that Dr. Ian Wilmut successfully cloned a lamb* named Dolly from a grown-up sheep. So people call him the “father” of Dolly.
Tony: In fact, the word “clone” means to produce the “same” animal by taking cells* from a
grown-up one. I think, if we know how to do cloning, we need only to keep a small number
of sheep, cows or horses.
Lana: What’s more, these days some people even want to clone humans. They have asked: Can we
clone ourselves?                                                       
Tony: It seems interesting. But do you think it possible to do that?
Lana: No, impossible! First, I think we cannot clone a dead person, because the cells in his body are dead already.
Tony: Then can we clone a living person?
Lana: Again no! You might clone yourself one after another, but it is only a copy, not a real you. It is only something, not a “human”.
Tony: Well, you mean that it is not a real human.
Lana: True enough! I think Dr. Wilmut would most like to make better animals, and it has nothing to do with human cloning.

科目：初中英語(yǔ) 來(lái)源：2011年北京市平谷區(qū)中考英語(yǔ)一模試卷 題型：閱讀理解

People cannot reach an agreement on the use of science and technology. For example, will radiation from electronic equipment destroy the environment? Should medical scientists change gene structures to prevent genetic disease or to create “more perfect” human beings? While people are arguing about these and others, technology continues to influence our everyday lives—the home, health and education, entertainment and communication, and so on.

   Some people carry on active social lives with computers —their own or the ones in public places like cafes, social centers, libraries, and so on. Communicating with others in chat rooms,  computer users can get to know people they might never meet in traditional ways. With live online video connections, two people with cameras in their computers can see and talk to each other from separate places.

   With modern telephone technology, most people stopped writing lettters—especially personal letters and notes. But now, writing to communicate has returned in electronic form, or e-mail, which is a way of sending messages from one computer to another. For some computer users, the wish to communicate intelligently or creatively with others makes them want to write better.

   Computer technology has also made it possible to run a house electronically. From turning lights on and off to starting the coffee and cooking the hot meal, computers are taking care of people at home. Many modern machines have computer chips that allow their owners to program them. For instance, you can “instruct” a microwave oven how to cook a dish. Most entertainment equipment operates with computer technology too. Computers can even start cars automatically so that on cold winter mornings you can get into a warmed-up vehicle and drive off.

   Although much of the technology in our everyday lives has good effects, there are some uses that raise questions. For example, are interactive media ( i.e., a combination of television, telephone, and computer) going to control minds, cause people to forget about family life and personal relationships? What effects will the genentic engineering of food have on people’s health? High-tech medical treatments can make a person live a much longer life, but can they improve the health and happiness of human beings? Only time will tell, but, in the meantime, science and technology will continue to move forward. 

1. What does the underlined word “ chips” mean?

A. thin pieces of potatoes  B. small holes    C. small pieces of wood   D. central parts

2.We can know from the passage that _________.

   A. technology never stops changing our everyday lives 

   B. with computers each of us can live a comfortable life

   C. people can do more activities with computers

   D. the more you use computers, the better you might write

3.What can we infer from the underlined sentence in the last paragraph?

A. The longer you live, the happier you are.

B. High-tech medical treatments can’t improve our health and happiness.  

C. High-tech medical treatments can’t help us with everything.

D.The writer questioned high-tech medical treatments somehow.

4.What is the best title for the passage?

   A. Science and New Technology        B. Computers Change Our Lives

   C. Everyday Uses of Technology        D. Only Time Will Tell
